N represents a set-screw for securing said gage to any adjusted position. As constructed, the ears 0 of the brackets B B project up vertically and serve as a stop, against which the paper rests during the perforation.

In Fig. 4 I have shown a modification which only differs from the device of Fig. 1 in that the screw shown as attaching the bracket B to the base in Fig. l are omitted, and the other end of the rod E is supported in a hanger I. It is obvious that either one or both brackets may be adjusted on said rod to secure the desired mutual adj ustability without departing from my invention. For convenience of attachment and detachment the end of the rod is secured in the hanger I bya thumb-screw. II represents the adj listing-screw on bracket 13. In practice the left-hand bracket is normally fixed relative to the coacting bracket; but they may be mutually adjusted, if desired, and this form has certain conveniencesto wit, the facility with which it can be put together or taken apart, which renders it very useful.

P represents a cap having a stem 6 screwthreaded into the front end of the arm C and vertically over the punch. It is provided with an orifice or passage registering with the orifice 0, so that the cuttings of the paper will be passed up into the said receptacle. R represents a cover for said cap. This cap is shown as detachable for convenience of construction. The essential idea of this feature is the employment of a receptacle for the cuttings, properly located relative to the female punch member, which receptacle may or may not be provided with a cover without departing from the invention.

IIaving described my invention, I claim 1. In a paper-perforator, the combination of a pair of brackets mounted upon a longitudinal guide-rod, one of said brackets being adjustable thereon, pivotally-connected male and female members carried by each bracket, levers for operating said punches, a rod connecting said levers and one of said levers being adapted to slide thereon, substantially as specified.

2. In a paper-perforator the combination with a suitable base, a pair of brackets each provided with pivotally-conneeted male and female members, operating-levers for said punches, a longitudinal guide formed on said base, one of said brackets being adjustable thereon, and means connecting said levers adapted to simultaneously operate the same, substantially as specified.

3. In a paper-perforator the combination with a supporting-base of a pair of brackets mounted thereon, each provided with pivotally-connected male and female members, operating-levers therefor, a longitudinal guide formed on said base, a connecting-rod passing through the lever members, one of said brackets being adjustable on said guide and means for securing said bracket in position, substantially as specified.

4. In a paper-perforator,the combination of a pair of brackets mounted upon a suitable base, a longitudinal guide-rod supported by said brackets and mounted on said base, one of said brackets being longitudinally adjustable thereon, means for securing said bracket in its adjustment, pivotally-connected male and female members mounted upon each bracket, levers for operating the same, a rod connecting the said levers, and paper-guide supports mounted in front of said brackets, substantially as specified.

In testimony whereof I have hereunto set my hand.
